Does the early patches of the game run quicker than the newer patches? example: if patch 1.27 had 5 extra fps than patch 1.52 on the same hardware.

I own an ps2 with this game and would love to speedrun it and have realised the lack of runs and community with the ps2 version of the speedrun is quite annoying because i want a competitive playing field and it dosnt feel rewarding beating 2 people insted of many like there is on the ps3

and here comes the question: why isnt the ps2 and the ps3 not in the same catagory?
